Another splendid piece of entertainment, in two parts, from Zaha Hadid. First she held spellbound a book launch audience at the Hayward Gallery (where her design for the Century of Art and Fashion show has won rave reviews). Zaha came complete with sequinned slippers, a mike that worked, and a sympathetic interviewer (my erstwhile colleague Marcus Field), plus a man from Thames & Hudson who sat on stage, said nothing, and appeared to be some sort of mute minder. Then chez Zaha, where we had that most traditional of Kensington main courses: whole spit-roasted sheep. I did not notice Giles Worsley there, but the Great Critic had this to say in the Telegraph, following a review of the Hayward show: 'Hadid's design is a triumph . . . it made me wonder whether there is more to her architectural designs that I had thought.' Right on!
